Running the test suite for a +newly built package is a good idea because it can provide a <quote>sanity +check</quote> indicating that everything compiled correctly. A test suite +that passes its set of checks usually proves that the package is +functioning as the developer intended.

For example, +the test suites for the core toolchain packages—GCC, Binutils, and +Glibc—are of the utmost importance due to their central role in a +properly functioning system.

There can be no escaping the fact +that the host system always exerts some influence on the tests in that +chapter, often causing inexplicable failures. Because the tools built +in <xref linkend="chapter-temporary-tools"/> are temporary and +eventually discarded, we do not recommend running the test suites in +<xref linkend="chapter-temporary-tools"/> for the average reader. The +instructions for running those test suites are provided for the +benefit of testers and developers, but they are strictly +optional.</para></note> + +<para>A common issue with running the test suites for Binutils and GCC +is running out of pseudo terminals (PTYs). This can result in a high +number of failing tests.
